Recommended for nearly all chemicals, solvents, acids, bases, steam and extreme heat. Not recommended for molten alkali metals and some fluorinated solvents.\u003c\/p\u003e\u003ch3\u003eYou Can Do This Repair\u003c\/h3\u003e\u003cp\u003eClean the groove and mating surfaces and check them for nicks or burrs. Lubricate the new o-ring, then roll it into the groove without twisting it; pass it over threads or sharp edges on a piece of tape or a plastic sleeve so it is not cut. Tighten to the normal torque. A correct o-ring seals by squeeze, so more torque is not better.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePro Tip:\u003c\/b\u003e A thin coat of \u003ca href=\"https:\/\/beaverislandparts.com\/products\/aqua-flex-food-grade-silicone-lubricant-50g\" target=\"_blank\" rel=\"noopener\"\u003eAqua Flex\u003c\/a\u003e silicone lubricant eases installation, protects the seal on first start-up and extends its life.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eShipping:\u003c\/b\u003e This part is special-ordered and packed for you.

Size, not brand, determines fit for standard o-rings. Measure the old o-ring's inside diameter and cross-section with calipers, or better, measure the groove, because a used ring stretches and flattens. Match the material to the fluid: the right size in the wrong rubber will still fail.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eQ: What is FFKM Perfluoroelastomer good for?\u003c\/b\u003e\u003cbr\u003eA: It is suited to nearly all chemicals, solvents, acids, bases, steam and extreme heat. Avoid molten alkali metals and some fluorinated solvents.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eQ: Can I install it myself?\u003c\/b\u003e\u003cbr\u003eA: Yes. Most o-ring replacements take only a pick tool, a clean rag and lubricant. Release pressure, drain the system if needed, remove the old ring, and follow the installation notes above. If it is your first time, take a photo before you take anything apart.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eQ: When will it ship?\u003c\/b\u003e\u003cbr\u003eA: It ships from our facility in about 10 business days, then transits by the carrier service you choose.\u003c\/p\u003e","brand":"Beaver Island Parts Company","offers":[{"title":"1 (Single)","offer_id":48853429977293,"sku":"OR.040.1.BI.STD.FF75","price":130.99,"currency_code":"USD","in_stock":true},{"title":"2-Pack","offer_id":48853430010061,"sku":"OR.040.2.BI.STD.FF75","price":237.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/8110\/0237\/files\/IMG-027_ba1cd4b0-d48e-4011-902e-b34be3a87741.jpg?v=1794347629","url":"https:\/\/beaverislandparts.com\/products\/as568-040-ffkm-perfluoroelastomer-o-ring-75a-durometer","provider":"Beaver Island Parts Company","version":"1.0","type":"link"}
